As part of Road Trip 2015, CNET visits Mcity, a 32-acre fake city in Michigan designed to test self-driving cars' navigation and communication abilities -- and to keep research from migrating to Silicon Valley.

The Sony Xperia Z3 Tablet Compact's wealth of power, its skinny, waterproof body and decent screen make it a good option to consider if you're after a portable tablet. Although its screen resolution doesn't put it over its competitors, its ability to play games from your PS4 -- although not perfect yet -- gives it a unique selling point.

While the battery is a concern, the Xperia Z2 Tablet is still a good-looking slate that's loaded with more than enough power for anything you're likely to throw at it. It's a good choice if you're looking for a more affordable iPad alternative with 4G LTE -- particularly if you've ever lost a gadget through water damage.
